Enter Nix Shell Step does not reflect failure status back to github

[medoror-mo]

Problem Description: Subsequent pipeline steps are failing due to misconfigured attributes in my Nix configuration within the Nix flake. Ideally, I would prefer the pipeline to fail immediately at the Enter Nix Step when any errors occur to prevent unnecessary downstream failures.

Proposed Solution: Modify the Enter Nix Step to exit immediately upon encountering an error in the Nix configuration, ensuring other pipeline steps aren’t triggered when prerequisites are unmet.

I've just released v1.2.1 with a fix for this. Thank you so much for reporting it.
